Back to School STEM Activity: Paper Hydraulic Lift Challenge (BTS20) | Engineer

🚡 Back to School STEM Activity: Paper Hydraulic Lift Challenge (BTS20) Discover fluid power mechanics, Pascal's Principle, and mechanical advantage! The Paper Hydraulic Lift Challenge (BTS20) challenges middle school student teams to act as mechanical engineers, constructing a paper scissor-lift mechanism powered by a water-filled syringe hydraulic system to raise heavy payloads vertically. Students explore Pascal's Principle, fluid incompressibility, scissor linkage mechanics, hydraulic displacement ratios, and force-distance trade-offs! 📦 What is Included in This 2-Page Packet: Page 1: Student Mission Card & Blueprint: Real-world fluid power engineering and heavy machinery scenario. Clear material constraints box (2 syringes, tubing, water, cardstock strips, brads, platform, payload weight, 10 cm lift goal). Dedicated Hydraulic Piston & Scissor Linkage Schematic sketching zone for planning master/slave syringe placements, fluid conduits, and pivot points. Page 2: Testing Log & Scientific Reflection: Structured Data Testing Table: Track fluid volume, vertical lift height in centimeters, and supported payload mass across 3 trial runs. Applied Math Connection: Calculate mechanical piston displacement ratios ($\text{Input Distance} / \text{Output Lift Height}$). Physics Reflection Questions: Analyze Pascal's Principle, liquid incompressibility vs air elasticity, scissor linkage geometry, and force/distance trade-offs. 📐 Core STEM Skills Covered: Fluid Mechanics, Pascal's Principle & Incompressible Hydraulics Mechanical Linkages, Scissor Mechanisms & Force Transmission Data Logging, Metric Lift Measurements (cm), Mass Math (g), and Displacement Ratios System Troubleshooting and Fluid Power Calibration 💡 Why Teachers Love This Resource: High-Impact Mechanical Physics Lab: Watching a paper scissor lift smoothly elevate a heavy payload with fluid power is an unforgettable classroom moment! Accessible Materials: Uses simple plastic syringes, clear tubing, water, cardstock, and metal paper fasteners. Clean 2-Page Layout: Keeps student schematics, displacement ratio math, and fluid physics reflections organized on a single front-and-back printable sheet. Format: High-resolution, print-ready PDF format (2 Pages).
